Snow Raindrops Detection Sensor Module Compatible With Arduino by Atomic Market

  • $7.99

Manufactured By Atomic Market
Operating voltage 3.3V-5V
Sensitivity can be adjusted via potentiometer
The sensor uses the FR-04 high-quality double-sided materials, King Size 5.0 * 4.0CM, and with the surface of the nickel plating treatment, against oxidative, conductivity, superior performance and longevity;
Small board PCB size: 3.2cm x 1.4cm
Wide voltage LM393 comparator

How to use:
Connected to 5V power supply, the power indicator light, sensor board is not water droplets, DO output is high, the switch lights off, dropping on a drop of water, DO output is low, the indicator light switch, Brush off the the above water droplets, has returned to output high state. . . . AO analog output can be connected to the microcontroller AD port to detect the size of the drops in the above rainfall. DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain.

Connection mode:
1. VCC: positive power supply (3-5V)
2. GND: negative one.
3. DO: TTL switching signal output
4. AO: Analog signal output
